Hello, laura.

I have the same situation with you.

When i discussed with my company that they should reimburse the difference between ADW and basic salary for that particular day (Statuotory Holiday and annual leave), they said that the ADW should be compared with (Basic salary + commission)/ how many days for that particular month.

I have enquired to the Labor department and they cannot give me a clear answer.

Have you filed a case to labor department?
